To all whom t may concern. I

Be it known that I, WrLsoN HATCH TUCKEIga citizen of the United States, residing in Montclair, Essex Co., New Jersey, have invented certain new and useful Improvements in Cold-Storage Installations, of which the following is a full, clear, and exact description.

My invention relates to cold storage installations and particularly to the type in which furs and other articles which it is desirable to protect from moths, are stored.

One object of my invention is to provide such a cold storage installation in which cold air is made to circulate continuously without the aid of a fan or other mechanical means. K

Another'object is the provision of means whereby fresh, pure air may be substituted for the vitiated air within the storage compartments, when necessary.

Still another object is the provision of v means whereby the loss due to the escape of cold air when an attendant enters the storage compartments is reduced to a minimum. Other objects and advantages will appear from the description and claims which follow.

The single sheet of drawing illustrates a longitudinal section of my cold storage installation. In the drawing 1 represents the cooling or refrigerating chamber in which is located the refrigerating coil 2, through which a suitable refrigerating tluid such as ammonia circulates. The refrigerating chamber is provided with two inlet openings 3, 4, located in the upper portionsofvthe opposite side walls and with the two outlet openings 5, 6, located in the lower wall. Each of these-openingsis provided with a suitable door for closing the same. Adjacent the cooling chamber and extending partially thereunder on either side are the storage compartments 7, 8. These compart-` ments are separated by the wall 9 in which is located a door 10, which may be opened to allow the two compartments to communi-` cate with each other, as will be hereinafter described. In the outer walls of the storage compartments 7, 8, are the doors 11, 12, respectively, which may be utilized to permit a person to enter therein. As clearly shown in the drawing, my installation extends throughout two stories. The doors 11, 12 are located near the top of the second story thereby enterinr for a purpose which will appear hereinafter. Within the storage compartments are located suitable clothes racks 18 supported on cross beams 14, which beams also vserve as walking beams for the attendants.v The ladders 15 are provlded to convey the attendants to the high racks. The doors 16, 17, 18, 19 are provided in the ceiling, whereby pure air may be substituted for the vitiated atmosphere within the installation, when desired. The doors 16, 17 are also useful as an exit for the steam, when hot water is run through the cooling pipes to `remove the frost from the exterior thereof. The normal operation of this installation is as follows: The air within the cooling chamber as it is reduced in temperature, sinks to the bottom of the chamber and escapes through the outlet openings 5, 6, the storage compartments 7, 8, respectively. After passing into the storage compartments, the air is slightly heated and therefore rises to the top of the storage compartments and again enters the cooling chamber through the inlet openings 3, 4. In this Way a. constant circulation of cool air is maintained from the cooling chamber through the openings 5, 6, through the storage compartments 7, 8, and thence into the cooling chamber through the openings 3, 4. By locating the doors 11, 12 in the position shown, the amount of loss by reason of the escape of cold air, when the doors are opened to permit the entrance of the attendant, is reduced to a minimum. It the doors were placed at the level of the first floor, a Very much larger amount of cold air would escape because at that point the general direction of the circulation is horizontal, and also because the difference in temperature between the outside atmosphere and the air of the storage compartments is greater at the bottom than it is nearer the top. At the point where I have located the doors, on the other hand, the general direction of the circulation is vertical and the dilerence in temperature is less, so there is very little tendency for the cold air to escape when the doors 11, 12 are opened. If it is found to be inconvenient to locate the doors at the places indicated by 11, 12, they maybe located at the places 11', 12. When so `located the advantages above pointed out are still present, but to a slightly less degree.

If it is desired to use but one storage comso thatfresh air enters the coolingchamber through doors 16, 17 .and .passes thence through the openings 5, 6, forcing-thelvitiated a1r out through the doors 1 8, V19'. After this operation has been oarried'on for a' short time,the .vitiated air ofthe stora f compartments willl have been complete y replaced by fresh pure air. When this been accomplished the doors 16,17, 18, 19' are closed, and the doors 3, 4, 'opened toy allow the air' tocirculate e'ntirelj7- within the installation.

The advantages of my installation are obvious,- rom the above. I do not desire i I to limit myself to the particular embodi- `ment 'shown herein, but obviously many changes may be made therein without departingfrom the spirit of my invention. What I claim is; 1. In a cold storage installation, the com? bination of a plurallty of adjacent'communicating storage compartments having a common side wall provided with means for V`putting the said com artments into commun1cation, a single re vcated partially within each of said compart- 40.

gerating chamber lomexits adjacent the tops thereof and pro- Y vvided adjacent its bottom with a plurality of outlet openings, one of which communicates with one. of said compartments, and,

adjacent its top, with a pair of inlet openings one of which communicates with one 'of said compartments, and a closure foreach of said openings, whereby each compartment may be independently supplied with cold air through its corresponding outlet opening, or a single compartment may be supplied with cold air through both of said outlet openings, as desired.

2. In a cold storage installation, the comi bination of a plurality of adjacent communicating storage compartments lhaving a putting said compartments into communication with each other,l each compartment` being provided adjacent its top with a 4dooredopening for the entrance of an attendant therein, a single-cooling chamber located partially within each of said compartments adjacent the tops thereof, and provided, adjacent its bottom, with a plurality of outlet openings, one of which communicates with one of said compartments, and, adjacentits top, with a plurality of inlet openings, each of which communicates with one of'said compartments, and a clof sure for each of said openings, whereby each com artment may be independently sup phed with cold air through 1ts corresponding outlet opening, or a single compartment may be supplied with cold air through both of said outlet openings, as desired, said chamber` being provide with a door opening to the chamber whereby pure air may'V be admitted thereto.
